A customer wants to mail a package.
The postal clerk determines the cost of the package to be $18.95, but only
6¢ and 9¢ stamps are available. Can the available stamps be used for the exact amount of postage for the package?
Why or why not?

Please note that your subject is NOT "college."

divisors of 18.95 include 5;3.79 So you need to see if 3.79 can have divsors:IT turns out 379 is a prime number, and has no factors, so no possible way to make stamps from anything except a 3.79dollar stamp.

Thank you
